Aproach to Wangen-Lachen was a bit tricky because the downwind leg has to be flown very close to the runway (see this link). We flew it almost the way it was suggested . The landing was rather tough. This was the shortest runway I ever landed on and to make it even worse on the approach I was too high and did not manage to touch down shortly after threshold.
On the way back it was quite busy in the air (that was Saturday in the middle of "long weekend"). Arrival back to Grenchen was quite challenging, especially that we were flying HB-CGU which does not have intercom (only loudspeaker and hand mike).
In Grenchen there are 3 parallel runways. Concrete runway in the middle and 2 grass strips on both sides. During our approach to concrete runway 25 we had another plane next to us on short final to runway 25L, it felt a bit strange.
